* Revisions :
* $Log: actions.c,v $
- * Revision 2.0 2002/06/04 14:34:21 jongfoster
- * Moving source files to src/
+ * Revision 1.32.2.6 2006/01/29 23:10:56 david__schmidt
+ * Multiple filter file support
*
- * Revision 1.33 2002/05/26 12:14:19 roro
+ * Revision 1.32.2.5 2005/06/09 01:18:41 david__schmidt
+ * Tweaks to conditionally include pthread.h if FEATURE_PTHREAD is enabled -
+ * this becomes important when jcc.h gets included later down the line.
+ *
+ * Revision 1.32.2.4 2003/12/03 10:33:11 oes
+ * - Implemented Privoxy version requirement through
+ * for-privoxy-version= statement in {{settings}}
+ * block
+ * - Fix for unchecked out-of-memory condition
+ *
+ * Revision 1.32.2.3 2003/02/28 12:52:10 oes
+ * Fixed memory leak reported by Dan Price in Bug #694713
+ *
+ * Revision 1.32.2.2 2002/11/20 14:36:55 oes
+ * Extended unload_current_actions_file() to multiple AFs.
+ * Thanks to Oliver Stoeneberg for the hint.
+ *
+ * Revision 1.32.2.1 2002/05/26 12:13:16 roro
* Change unsigned to unsigned long in actions_name struct. This closes
* SourceForge Bug #539284.
